Git revision can refer to the at91bootstrap repo itself used to generate
the patches (in this case .git exist) or to a parent repo (wr-switch-sw)
that we used with patches (In this case we need to pass git value using
exported variable) because no .git folder when creating the
at91bootstrap folder.

WR_INSTALL_ROOT and WR_LIB are folders to install library while using NFS.
They should only be used with install command and not during linking step
because they can be out of sync.

The HDL sources can be found in wr-switch-hdl repo with the tag wr-switch-htl-v3.3

On some swtiches the management port was not accessible, most likely
for wrong timing in overall setup.  Removing and re-loading the
usb gadget module seems to fix the problem.

v3.3 gateware has reduced number of global clocks by using regional clock nets
for first 4 GTX. Software needs to compensate additional delays.

In Grand Master mode it takes longer to lock PLLs to external source, therefore
HAL becomes ready later.

The script wrfs_mnt can be used for remounting rootfs to update the
configuration of the switch.

0. From power until linux has boot the led is unpowered
1. We first set init it before flashing FPGA => LED is yellow.
2. Then when the HAL start => LED is orange
3. WR is setup => LED is green

Despite being "obivously right", the previous commit, didn't work.
I didn't identify the reason of the permission problem but changing
it right before tarring works.

Previous commit is already in master, and master is holy, so here's
another commit.

Don't filter by VID mask on. Such filtering is not a default 802.1Q behavior. TODO: add optional config.

Override dst_port_mask when ureq received and there is existing MAC Entry. Update time when updating existing entry

* flash-wrs: add gateware selection to only use 2 HDL binaries because the RAM size is not big enough to extract 4 HDLs during flashing
* build: add the new gatewares with PWM and LX240T support for 18ports & 8ports
* userspace: Select the proper gateware to load on fpga using the shw_ver tool and the i2c dip switch on miniBP
